TEMPORARY BOOKBINDING.

Specification of Letters Patent.

Application filed March 5, 1909.

Patented Sept. 27, 1910.

Serial No. 481,456.

T 0 all whom it may concern:

Be it known that I, .Ciunnns F. MoBnn, a citizen of the United States,residing in Athens, county of Athens, and State of Ohio, have invented anew and useful Improvement in Temporary Bookbindings of which thefollowing is a specification.

The object of my invention is to provide a means for temporarily bindingloose sheets of paper, and the like, between covers, the whole beingdesigned to constitute a temporary book and the covers being adapted tobreak back and open, to permit of access to the temporarily boundsheets.

A further object is to provide a clamping device, designed to fit overone end of a number of loose sheets of paperthe said sheets having beenevened on the end receiving the clamping deviceand to be clamped thereonand to thereby constitute a temporary binding which will securely holdthe sheets of paper together in book form.

Another object is to provide such a device in a simple, strong, durableand practically inexpensive, construction.

My invention consists of certain details of construction, hereinafterset forth, pointed out in my claim and illustrated in the accompanyingdrawings in which Figure I shows a perspective view of my device and thetemporarily bound book secured therein; Fig. II shows a side elevationview of the same, the upper cover and a portion of the leaves beingthrown back; Fig. III shows an enlarged front elevation view of mydevice and the book clamped therein; Fig. IV shows a detail view, inseotion, of my clamping device and the temporarily bound book securedtherein; and, Fig. V shows a detail view, in section, of a portion ofthe clamping plate I employ.

My clamping device consists of a frame, adapted to fit over the ends ofthe evened sheets of paper, said frame consisting of an upper plate 10and a lower plate 11, the said plates being joined at their rearextremities by a member 12. The plates 10 and 11 are designed to be ofequal size, and parallel, their length being somewhat greater than thewidth of the covers, designed to be placed on the book, and the saidplates are joined by the member 12 in the manner shown in the drawings.The member 12, is

designed as an evener, for the ends of the covers and leaves when theyare projected into my device, for the purpose of being bound. Verticallymounted between the plates 10 and 11, and having their bearings therein,as shown in Fig. IV of the drawings, are two screw threaded shafts, 13and 111:, rach being provided, on their upper extremities above theplate 10, with means 15 and 16 respectively, for rotating them. Theshafts 13 and 14: are mounted, one near each end of the frame, asclearly shown in Fig. 111 of the drawings, and supported between them isa plate 17, said plate being of equal length with the plates 10 and 11,and being provided near each of its ends with screw threaded orifices18, which are designed to receive and engage the shafts, 13 and 14:respectively. The plate 1.7 is designed to ride up and down on theshafts 13 and 14, and, as the shafts 13 and 14 are similar in everyrespect, it is obvious that if they are rotated uniformly the plate 17will be parallel with the plates 10 and 11. However, a slight variationin the uniformity of the rotating of the shafts 13 and 1 1, while itmight throw the plate 17 out of the parallel plane with the plates 10and 11, will do no par ticular harm other than might be occasioned bythe binding of the plate between the shafts, and it is obvious that thiscan be easily and speedily remedied.

The lower cover, of the book to be bound, is comprised of two sectionsjoined together so as to provide a hinge, which is designed to beslightly in advance of the forward edge of the lower plate 11, when thebook is engaged by my clamping device, as shown in Fig. 1V, and theupper cover of the book is composed of three sections joined together bya flexible binding, as shown in Fig. IV, in such a manner that the rearhinge will be slightly in advance of the forward edge surface of theplate 17, and the forward hinge will be a short distance in advance ofthe rear hinge. The purpose of the double break in the upper cover is topro vide for that portion of the cover, between the two hinges,projecting upwardly, in a vertical plane, or thereabout, so as toproject the second hinge above the plate 10, and thus it is obvious thebalance of the cover may project rearwardly from the second hingewithout any interference from the plate 10.

In practical operation the lower cover is inserted in the clampingdevice in the manner shown, the rear edge surface of the cover engagingthe forward surface of the member 12. The sheets of paper to betemporarily bound are evened, with respect to their rear edges, andplaced in my clamping device immediately on top of the lower cover, asshown, and the upper cover is then placed thereon. The shafts 13 and lffare then operated, simultaneously and uniformly, in such a manner as tocarry the plate 17 downwardly, until it engages the upper surface of theupper cover of the book and the plate is firmly clamped thereon.

If desired small hand wheels, or any other means, may be used instead ofthe rotating means 15 and 16, without altering my invention theprincipal feature of which is to provide a means for rotating the shafts13 and 14 and to thereby cause a downward or upward movement of theplates 17.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States is:

A temporary binder comprising in combination, a U-shaped frameconsisting of upper and lower horizontal plates and a rear verticalevenerplate joining said upper and lower plates, threaded shafts looselyand vertically mounted to project through said upper and lower platesnear the ends of the latter and parallel to said evenerplate, atraveling follower plate threaded on said shafts and movable thereby,and flexible covers receivable between said shafts and between saidupper and lower plates, whereby said evener-plate may serve tostraighten said covers and interposed pages and said follower-plate maybe clamped upon said covers and interposed pages.
